The present invention is concerned. with the proportions being substantially that outthe provision of a mixture which may be lined above. poured into the radiator of an automotive v In some instances I find it desirable to use vehicle, and which will crystallize around a dye or other ingredient in connection with any openings in the radiator to efiectively the formula. For instance about three fluid stop leaks through the openings. drains of caramel dye might be used in order Solutions for performing the same general to disguise the exact ingredients of the mix- 60 purpose are at present. on the market, but ture.

their efieotiveness is very temporary, and The manner of using the mixture is sub- 10 they are merely used to stop aleak until stantially as follows. If a leak occurs in a such time as the car may be taken to a reradiator, about 'apint of the mixture is pair shop. The solutions which are at prespoured into the radiator while the water is 65 ent in use are efiective for a day or two, hot. The engine is then run for a few after which the hole in the radiator re-opens. minutes, causing the water to circulate. The

The mixture of the present invention offers engine is shut off. The mixture of the presa much more permanent means for stopping ent invention will have been thoroughly disleaks, and has actually beendemonstrated to tributed through the water circulating sys- I retain its efiectiveness over a period of more tem and will crystallize around and seal than three months. Whatever holes there may be in the radiator.

7 A further object of the invention is to pro- Referring now more specifically to the vide a mixture of the general character above functions performed by the various ingredinoted which may be manufactured with coments of the mixture, I may state that the parative economy, which will contain no inwater is used simply to dissolve the other ingredients harmful, either to the water cirgredients and retain them in soluble form. 26 culating system or the'motor of an engine, The sugar acts as a crystallizing agent and and a mixture which will act both quickly will congeal or crystallize at the openings in and effectively to afford a substantially perthe radiator to form a seal. The fiaxseed manent seal for a leak. 7 acts as an expanding and clogging agent, While the particular proportions of the inplugging up the holes or leak openings so 30 gredients used are subject to a wide range of that when the sugar starts to crystallize variations, and while certain of the ingrearound the openings, the presence of the flaxdients might be replaced by equivalents, I seed will cause a crystalline seal to be rapidly have found that the following formula probuilt up to cover the whole opening, and the duces a highly effective mixture, and that in expansion of the flaxseed will greatly facili- 35 a preferred embodiment of the invention, tate this process.

substantially the proportions listed below are The salt acts as a hardening agent to renmost desirable. .der the seal tougher and more permanent. The formula is as follows: It is of course to be understood that other 1. 16 ozs. water, crystallizing agents, expanding and clogging 40 2. 4 ozs. sugar, agents or hardening agents might. be sub- 3. 2 ozs. flaxseed, stituted for the sugar, fiaxseed or salt,

At this time the various the system, it will ooze out through the ingredients with the exception of the fiaxholes in the radiator, and tend to form a seed will have become thoroughly dissolved sticky bed around the holes, Contact with 50 and the mixture will be ready for canning or the relatively cold air. at the holes will cause bottling. Preferably the mixture is put up the sugar and salt to crystallize, and an efin pint cans, and either large or small batches fective seal composed of sugar, salt and of the solut on may be mixed at one time, fiaxseed will gradually be built up to completoly seal the hole in the radiator. It may be noted that the operation oi? forming the seal is effected very rapidly.

Obviously various changes might be made in the exact materials usetl, or in their exact proportions Without departing from the spirit and scope of the present invention.

I claim:
